To all who/u if may concern.

Be it known that we, Hicxuv lli-11:51AM and Join' S. l). Anno, bothcitizens of the United States, residing at Baltimore and Highlandtoun,in the count v of Baltimore and State ot' Maryland. have invented neanduseful Improveiiieuts in Apparatus for Assembling' Formed Blanks, ot'which the following is a specification.

This invention relates to improvements in apparatus t'or assembling'formed or shaped members or parts of metallic containers, such forinstance as cans, boxes and the like, pertainimgl more lmrticularly toapparatus for assembling the bod)r and lid or cover and in which thecover is hinged to the body portion. each member carryingelements ot'the hin While the present invention is adapted to operate in connectionwith containers of various forms. thc embodiment of apparatus disclosedherein as exemplifving' the general invention, is designed moreparticularly for the assembling ot' containers in which the bodies aremore or less oval in cross-sectional parallel flat sides with roundedends`the cover and body portion connected on one of the longer sides ofthe container member. The members are generally formed sepai'atcl)Y andthe shaped parts are then brought together and assembled. his generaltype of container is commonly employed in connection with the packagingof tobacco products.

To provide the assembly the body portion is generally formed with spacedears through which a pintle extends on a line parallel to and spacedfrom the end of the,

'body portion, the cover having a pluralityof he members must e roughttogether with accuracy and in definite relation. the hooks entered andthe Specification of Lettrs Patent.

clenehinpr tool brought into action to clench the hooks on the insideot' the bod)v portion. This necessitates assembly ith the cover in anopen or i a general cycle simple and ettilie present invention isdesigned to meet t e various problems present in producing these resultsincluding that of large capacity, beiingr especially adapted for use asan auxiliary to a bod'v forminlgr machine altiough not limited in thatrespect. To indihe capacity. it ma y be noted that the presentapparatusl is designed to take care of the product ot' a. machine forforming the bodies`ivithout lbottoms`the present apparatus ivorkinpr insynchronous Ystep with `such machine. presentingr a cover, assemblingthe cover und body portion. clenching hooks. closing the cover andadvancing the completed assembly during the period of formation of thebody member on the forming` machine. Furthermore, these several at asingle station,

so that the entire manipulation required in producing the apparatusproduct takes place while the elementsf-the body portion and cover-arein this station, thus reducing the positioning' necessa` to required ininitially presenting the parts to the station. As a result, not only is'large capacity provided, but the .apparatus is of such generalformation as to ber of operating parts partiallyr open position andmoveformed Ain such manner as to reduce the amountJ of wear to a minimumand hence reduce the oostof the 11p-keep of the apparafully described,illustrated in the accom panying drawings, and more particularly pointedout. in the appended claims.

For the purpose of illustrating the general principlesv of the presentinvention, we have shown an embodiment capable oi'. and adapted to applya shaped cover to the open cud oi the shaped body portion ot acontainer. the shape referred to being indicated in Fig. 1G. in which liindicates the body portion 'formed with parallel side walls androundedMends. the cover being indicated at C and being. adapted toextend over and overlap the walls; ol the open ond of the body portion.'l`ho opposite end ot' the body portion may have a bottom securedthereto, although. in the disclosure shown in Fig. 1, the appariitus isdesigned to operate in connection with bodir portions onto which thebottom has not been applied at the time ot' the placing in position ofthe cover. the body portion forming,r machine, indicated at .\l inFig. 1. being adapted to produce a blank of tho desired contour andhaving its ends open. an arrangement which can he produced under largecapacity conditions.

As shown` the body portion has one ot' its side walls cut-away as at Iand provided with spaced ears b' through which extends a pintle j. thisarrangement being, provided in advance of delivery of the bod)Y blank-whereinafter referred to as a blank for purposes of explanation. thecover blank being indicated as a cover for similar reasons. The cover,is provided with hook shaped ears e spaced apart and arranged to beinserted beneath the exposed portions of the pintle, these hook earsthen being' clenched around the pintlc. In the present invention, thishookingr and elenching action is followed by closing' the cover, hut itis rto be understood that this latter feature maybe omitted. it desiredwhere the exigencias ot use are such as to make it desirable to deliverthe assembled parts in unclosed condition. .For the purposes ot'illustration, it is assumed that the operation includes the closing ofthe cover so as to product` a configuration api proximately of the formshown in Fig. 18. Fig. 17 indicating the general positions andarrangement of parts on the completion of the cient-hing operation.

Before giving a detailed description ofthe structural elements of theapparatus, a brief description is iven of the general operation in orderth'at tile detailed structural description may be better understood, thelatter {ollowing, as far as possible, the travelY of the parts throughthe apparatus.

The blanks B are delivered to a runway of the apparatus with the longercross-sectional axis of the blank extending vertically, the pintleextending vertically at the advance end of the blank. The blanks areadvanced the cover 1s not clamped, the carrier 'cover to its closedposition,

ove, the runway by a step-bystep movement and may be delivered to therunway in any suitable manner, the drawings indieating,r 4this as takingplace through the action ot' thc discharging mechanism of the blankforming structure. It will be understood, ot course.y that this supplyof the blanks to the. runway may be provided manually.

he covers C are delivered to a cover hopper or chute by suitable means,which may be mechanical or manual in forni, the covers also having theirmajor axis extending vertically. The chute is arranged in such mannerthat a cross-section of the chute will have its length extending in adirection inclined to the direction of length ot' the runway, and it maybe noted that this length of the chute is also inclined to the directionof advance movement of the cover. In actual fact. the chute is soarranged that the projecting hook ears c will. during the advance of thecover, freely enter the spaces beneath the pintle, and the hook ears areso shaped as to permit this positioning while the cover is partiallyopen.

The Ybody blanks are, through the action of the advancing means of therunway, what may be considered as the hinging or manipulating statiomthe advance movement bringing a forward edge of blank into proximity toor in contact with the clencher member which advances as the blankadvances and which, at the time the blank reaches its proper position,eX- tends across the path of travel of a Wall of the blank, thuspreventing advance of the blank beyond a predetermined point.

The cover blank carrier at the bottom. of the chute is normally in suchposition that at this time, forming what may considered a loose casingforming a variable channel into which the cover may freely enter fromthe chute. At a proper time. the walls of this are closed into, positionto is then adits advance movement stopped as indicated, is shifted intoa clamped position.

The advance of the cover blank is so arranged that 'the hook ears ortongues will pass into proper position relative to the clamped blank B,and when the hooks are properly positioned` the clencher member is madeactive to curl the hook ends about the pintle. after which a lid closerelement is brought into activity to move the secnredl y the elenchermember, which, during its cycle of operation. extends between the openend of the body blank and the cover. being Withdrawn. After the coverhas been closed, the closing mechanism is Withdrawn to place itinnorkmal position in the carrier to receive the of a` blank and thus,during the advancing' succeeding cover blank, thc body portion of thecontainer-ca,rrying the secured cover in its closed .position-isunclamped, and the advancing mechanism advances the product out of theway oi the succcedin blank.

ln addition. the arrangement is such that a cover blank is not permittedto enter into its advancing carrier excepting in the presence of itscorresponding body blank at the proper point in the advancin, r runway,thus permitting the mechanism instrumentalities to operate Withoutdamage in the absence of a body blank.

The entire assembly and closing manipulations are provided at vthehinging or manipulating station, being completed within the timerequired b f the advancing mecha- Anism to return to its blank receivingposition and then advance to position the blank into the manipulatingstat-ion, these operations, Where the apparatus is 'in synchronism witha blank forming machine, practically taking place in synchronism withthe .operation of said machine. In other Words, the time of assembly andcover closing at the manipulating station does not exceed the timerequired in the formation of the blank.

30 indicates the advancing;r runway for the body blank. VAs siown inFig. 4, this runway is in the form of a channel having o posing sideWalls 30" and a central bottom strip 30", these parts being suitably`secured on the top of a table-like frame Q5. Asshown, the channel is ot'materially greater width than thewidth ofthe blank. thus permitting theblank to be freely advanced Without liability ot' binding. sides ofstrip 30, are a pair of reciprocating bars or strips 31 1each of whichcarry a plurality of springl supported pawls 32 (Fig. 6), these vpawlsbeing' spaced apart in the direction ot' length of the bars at properintervals. As seen, the advance end of pavvls 32 is adapted to contactwith therear end movement of bars 31 push the blankor- WardVY to advanceit a `distance substantially equal to the length of reciprocation ofbars each pawl being so armovement of bars strip is s l prvated fromeach other'jinthe direction cilena-th of 130 the runway.

Pawls or lingers are also held against retrograde movement by pawlS 33.

Bars 31 are reciprocated by any suitable mechanism, that shown in thedrawings being in the form of a rotating shaftV 35, carrying a crankWheel B6 having a wrist pin 37 towliich is connected a pitnian 38. thelatter being suitably connected to bars 3l. ()bviously, this is but oneway in which the reci )rocating motion of bars 3l may bc obtained.

Shaft 35 forms the drive shaft for the apparatus and is driven from asuitable source, Fig. l showing this as a chain counection with asuitable mechanism of the body forming mechanism M, the apparatus. asheretofore indicated, being shown as a continuation of or an auxiliaryto a forming mechanism of this type, runway 30 being shown as extendingto a point where the blanks from the forming mechanism are delivered onto the runway where the. advance is produced step-by-step by the actionof pawls 32 and 33. As will be understood, the runway may have anydesired length, the number of sets of pawls employed being dependent onYsuch length. Similarly. the length of reciprocation of bars 31 will bearranged to Ymeet the desired conditions, the arrangements, however,being such that the blanks Will preferably be advanced in spaced apartrelation and. so. arranged that the advance movement of the blank whichis to be operated upon will leave it in position at the operatingstation.

Darin the advance of blank B to place the blan advance end at the properpoint in the operating station a -clencher member or tool 39 isadvanced, as presently described, into the path of travel of the blank,the tool thus forming a stop in the ath of blank movement, theadvancingmee ianisrn bringing the blank into proximity to or 1n contactwith thistool.

As heretofore pointed out the blank advaneesrlon `the channel sustantially central of the c annel, asshown in full lines in Fig. 4,after the blank has been advanced into p position relative to theclencher tool (or into-froment with any other suitable stop. meh Vismfor limiting the the blank 1s vance movementof the blank),

,extends through it housing shifted laterally into contact with one ofthe side walls 30 of the channel as shown in dotted lines in Fic. 1L,this shifting movement being provided by a shifting member shown as inthe form of a pair of pins l()A extendingI transverse to the channel andadapted to extend through suitable openings in the opposite side Wall 30of the channel, these pins. a suitable frame il and adapter to bereciprocated through the combined action of Springs 42 and a cam i3, thecam being mounted on a shaft 4l having a gear con nection with shaft3:3, and being adapted to control the movements of a vertical shaft 45,the lower end` of which carries airfarm 46 on which is mounted a roller4.7 adapted to contact with they operating edge of Icam 43, the upperend of shaft 4-5 havfing an arm -LS cooperating with a pin 49"'whichconnects pins 40. this hein a simple arrai'igement of a cam-controllingmechanism for controlling the operations of the pins. Obviously, thismechanism may be modified or substituted by other types of mechanism ifdesired. he advancing movements of pins 4.0 are provided by springs -llwhich, whenever the cam contigui-ation permits, will cause the pins toadvance and shift the blank to the dotted line position in Fig. 4, itbeing readily understood that the arrangement is such that no unduepressure will be applied to the blank, the pressure application beingyieldable but having sufficient power to carry the blank into itsshifted )osition and maintain it in such position during the subsequentoperations; The pins are retracted by the action of tlu' cam, thuscompressing the springsv which tend to maintain the roller 47 in contactwith the face of the cam Without, however, providing a pressure actionon the blank such as would be provided by a. positive cam action.

As shown in Figfl, shaft 44 extends in a direction inclined to thedirection of length of the runway. and this shaft forms the drive shaftfor the parts operativo in the operating or manipulating station. Theinstrumentalities operative in this station have elements whichreciprocate during the manipulating operations,.and these ele-V mentsgenerally reci rocate .at an angle inclined to the longitu inal andtransverse directions of the runway, the movements of these eleaients`being In' planes which are transverse to the direction of length ofshaft 44. For instance, the elencher tool 39 50 and o crates through anopenin formed in a si e wall 30. the directlon o len h of the toolforinin an obtuse angle wlth the direction ot' length of the runway inthe direction of advance of' the blalnk, while the advancing elementsfor the cover have their general dibeing supported in' rections oflength extending on the lines of an acute angle with respect to therunway length, beingr located to operate through an opening formed inthe opposite side wall of the runway.

he operations of clencher tool 39 are controlled by a cam 51 `ig. Q)tlii'ough a pivoted bell crank lever connection 52, one arm ot' whichcarries the groove 5l of the cam, the other arm being adjustablyconnected to the shank of the tool beyond housing 50,. cam 51 beinmounted on shaft 44. As will be noted, the cam preferably provides adwell to the tool turing inward travel of the latter, this dwell takingplace at the time of possible contact of the approa hing body b thetool, the timing arrangement being pret'- erably such that the bodyblank instrumentality delivers the blank into contact while the clenchertool is at rest.

`he ad preferablyY in the advance face of each 'linger figurationadapted to provide the clenching action on one of the ook ears of thecover blank when brought into contact therewith during the assemblingoperation.

54 designates a chute through which the cover blanks are delivered tothe operating mechanisms, this chute receiving the covers from asuitable source and in suitable inanner and having a configurationadapted to permit free downward travel of a cover blank with its majoraxis extending vertically. supported `in suitable manner and has itslower end preferably positioned above (Fig. 5 a clamping and advancinginstrumentality into which a cover blank drops and which is presentlydescribed in detail.

`he discharge otl cover blanks from the chute is perferably controlledin order that a cover blank may not be delivered into its having aconadvancing instrunwntality in the absen of a corresponding body blankto receive it,

this control being provided in order to prevent damage to coverblanks---the structure being such that any cover blank which may beadvanced will be subjected to the regular operations of the clenchertool. There no cover blank is present in the cover blank advancinginstrumentalities, the instrumentality cycle oi movements can take placewithout damage to operating parts.

ns control is provided by the following mechanism.

Mounted on a housing elements ot' the clamping strumentality operate.G5-through which and advancing inas presently explainedis asupplemental housing 56 (Fig.

1) inwhich is mounted a slidable member 57, the advance end ot' which isin the form of a linger 5T (Figs. 1, T and 10). this finger beingadapted to enter into chute 54 and opa ioller operative in being adaptedto rection may of an escapement mechaerate in the nature Member f7 ismsm for the cover blanks. adapted to be reciprocated, any suitablemechanism being usable for this purpose. Iowever, I hav shown thismember as provided wi'th a. pin 57 extending into an elongated slot 5U"in housing .36, this pin projecting above the top plane ot' the housingand be actuated by an arm 5S ot a )ell crank levei- :3b mounted on avertical axis. this form of connection being employed by reason ot' thiIdirection ot' reci procation ot' member 5T. the arrangement torming aloose connection by means of which member 57 can positively withdrawnfrom its position within thc chute by the movement ot' the bell cranklever. The movement of member :3T in thc opposite dibe provided in anysuitable manner as by a spring 5o.

Bell crank lever 5S is operated by the movements of a rock shat't (SUmounted in bearings carried by the runway and located above the runwayat a point where a body blank to be introduced into a manipulatingstation is required to pass. lQhat't (30 carries a crank arm G1 which isconnected to the other lever 5.8 by connectarm ot bell crank ing rod(i2, this arrangement causing rocking movement of shaft titl in onedirection to move lever 5S to provide movement of member 57 in onedirection. the returi movement of shaft o() permitting spring to becomeactive to return member .'T to its position within the chute.

The rocking movements of shaft (il) are provided by the movements ot' anarm (i3 carried by the shaft and having its free end provided with lll.the latter extendv of bars l-l. and being positioned to intersect thepath ot' travel of an mg of Fig. shown as blank. shifted arm (i8 from antical position`-due to t ie more or less weight action of the arm androllcr--to an inclined position as shown in this figure, the rollerresting on the upper portion oi' the blank. ln this position. member 5Tis in its withdrawn position. leaving the lowermost cover blank ofthechute i'ree to drop downwardly out oi' the chute. lVhen the body blankis advanced 'from the position shown in Fig. fi, arm (i3 will bereturned to its normal position as soon as roller (Si passes out ot'contact with the blank, this action, through the connections referrc(to, moving 125 permit member .ib to reenter the chute to prevent escapeof the succeeding cover blank until ariii 63 again shifted through theadvancing movements ot' a succeeding body blank. By locating arm (33 130approximately verand roller 64 at the point where the body blank isbrought to rest just prior to its being advanced to the manipulatingstation, the Withdrawal movement oi' member 57 will permit the escape ofthe particular blank which is to be assembled with the body blank thenlocated in this position, 4the positioned body and cover blanksadvancing toward the oint of assembly more or less concurrently. Sy thisarrangement, a steady feed of body blanks will provide a correspondingsteady feed of cover blanks. lV-hen, however, a body blank fails tomanipulate arm 63, bell crank lever 58 will not be moved and release ofa cover blank will be prevented.

The point where arm 63 and roller 6l are operative may be considered asa detecting station located in the path of advancing ,body blanks andoperative in the feed of the cover blanks.

The released cover blank passes downward into what may be considered asa variable channel lformed by the elements ol the clamping and advancinginstrumentality, this `channel normally being of a size to permit thefree downward movement of the cover blank into the channel, after whichcertain walls of the channel move into clamping relation with respect tothe blank, after which the clamped blank is advanced into the assemblingposition. The channel Walls are indicated more particularly in Figs. 5and 7 to `10.

65 indicates a member yield-ably suported in a bracket or support 66,member 65 aving a shank extension 65 extending through the bracket, saidextension having a collar 67 Within the bracket and between which andthe end of a bracket recess is located a spring 68 which tends tomaintain member 65 in its advance position. The ad- Vance face of member65 is inclined relative to the longitudinal and transverse directions ofthe runway, corresponding genen ally to the major cross-sectional lengthol' the chute. This member is located below the chute (Fig. 5) and formsthe rearvvall ofthe variable channel.

The front wall of the variable channel is formed by portions of twoelements viliich are indicated as a lid carrier 69 and a lid closer 70,thegenersl configuration of this portion of these elements being shownmore particularly in Figs. 12 and 13, the l-id carrier having a which isprovided with a vertically extend ing anvil face 69 and with a pair oi'spaced o sets 71 having forwardly projecting portions 71 one face'owhich forms partof 4the front `Wall of the variable channel. Theremainder of said front wall is provided by rejections 70, carried bythe lid closer and aving a face which normally extends in verticalalinement with the inner face of projection 71,\these faces beinginclined totapered ad Vance portion the general direction of length ofthe lid carrier and lid closer by reason of the fact that these elementsreciproca in the direction of their length and the positioned coverblank has the direction ot' length of its minor axis inclined to thisdirection of movement of these elements.

One of the side Walls of this channel is provided by a` face or anvil69, while the opposite side wall is provided by an element 72 shown moreparticularly in detail in Fig. 14, this element having a face 72 whichforms the fourth wall of the channel. This element is slidably mountedon lid closer 70, these two elements having a dovetail connection. whichwill permit relative sliding movements of element 7x2- which may beconsidered as a clamping element-and the lid closer, these parts beingshown as assembled in Fig. 15, element 72 being restrained through theaction of springs 73 which tend to retain face 72 in its clampingposition, the location of this face in this position however beingnormally prevented y the contact of a projection 72b on element 72 witha stop 74,carried by the frame of the machine, the ceo-action of member7 QL" and the stop being shown in Fig. 7.

As shown in said Fig. 7, face 69 is normally spaced a suitable distancefrom the side of the blank, the latter moving to this position in thevariable channel through the action of the lower end of the chute.Similarly, face 72 is normally spaced from the opposite side face of theblank, so that the c annel so formed is of larger dimensions than thecross-section of the blank, with the result that the latter will readilypass to po sition, coming to rest, when released from the chute, on asupport 7 5 (Fig. 10).

Clamping o the cover blank and advance of the clamped blank is providedby the advancing movements of the lid carrier and lid closer, the normalor inactive position of these elements being shown in Fig. 7. Theseelements advance in i nison during the clamping and cover advhncingmovements, the advancing movement of the lid carrier and lid closerbringing face 69 into contact with one side of the cover blank, thisadvance also acting to provide sullicient movement between member 72 andthe lid closer to canse face 72 to contact with the opposito side of thecover blank. the spring mounting of member 79. causing the blank to beclamped between faces 72 and 69, During the succeeding advance of theclamps.. plank, a tapered face 69 of the lid carrier contacts with theface of member 65. forcing said member rearwardly and out of the path oftravel of the clamped blank. This advance movement of the lid carrierand lid closer continues, and since the parts are soy ositioned that thehook ears of the cover 1b ank are brought to the body blank a rolleroperative in in registration with the openings ot' the latler throughwhich thehooks are to pass, this advancing movement causes the two partsto be assembled by hooking the cover ea rs beneath the pintle of thebody blank. As the. lid carrier clamping face is in the form of ananvil, the, movement of the cover blank to this position concurrentlyplaces an anvil structure in proper position for the hook clenchingoperation which is provided by the clencher tool continuing its advancemovement to turn the projecting ends of the hooks about the pintle. Thisposition coinpletes the advancing movement of the lid carrier without,however, stopping the advancing movement of the lid closer whichcontinues to advance from the position shown in Fig. S and brings ashoulder b into contact with the cover, the result being that furtheradvance movement causes the cover to be moved on its hinge to its'closedposition. Fig. 9 indicating the position of parts as the cover isapproaching such closed position. During this closing movement, theclencher tool is withdrawn to permit closing, and since the clamping orgripping action on the cover is by the action ot' springs 73, it will beunderstood that the positive pressure provided by shoulder 70b willrelease the cover from its engagement with face 72, ciently to permitthis action.

Upon completion of the lid closing action the clamping and advancinginstrumentalit v-\vhich. in the embodiment shown, includes the lidcloser-is retracted, leaving the runway free for the advance of theassembled struct-ure, the body clamping mechanism being released priorto such advancing movements.

The lid carrier and lid closer movements are controlled by theoperations of two cams or cam faces 75 and 76, cani 75 controlling theoperations of the lid carrier and cam 76 the operations of the lidcloser. The lid carrier is operatively connected to its cam by n eaul ofa bell crank lever 77. one arm of which is adjustably connected to theshank of the lid cai'rier. its opposite arm carrying the -cam groove 75ot' cam 75. The lid closer is operativelv connected to cam 76 b v apivoted bell crank lever 7S. one arm otl which is connected to the shankof the lid closer, the other arm carrying a roller operative inconnection with the cani groove 76 of cam 76.

.\s will be seen from Fig. 3. cams 75 and 7U diti'er from each other asto groove con tour in a portion only of the cani grooves, thisditi'ereuce providingr the different operations ot' the lid carrier andlid closer securing upon the completion of the clem-hing operation. thelid carrier dwelling for a lime and then returning to norm-.il position,wbilc th'e lid closer continues its advance element 72 yielding sutii'and then returns to its normal position, element 72 traveling in unisonwith the lid closer excepting during thc periods when projection 7:2b isin contact with stop T4.

The. Several mechanisms may be timed for operation to meet individualconditions, the arrangement of parts disclosed in the drawings beingsuch that the beginning of the lid carrier and lid closer movementstakes place shortly in advance ot' the beginning of the advance movementof the. clencher tool, the lid carrier and lid closer moving tocover-grippin position and advancing the cover blank while the clenchertool and body blank are advancing, the clencher tool dwell` ing slightlyas heretofore indicated, and then continuing its advance movement, thebody blank being clamped to position intermediate the time when theadvance 0f the body blank is stopped in proximity to or by the tool andthe time when the advance of the cover blank bringsits hooks intoposition to enter the body blank. If desired, the timing arrangement maybe such that a slight cover closing movement may be had in advance ofmovement of the clencher tool away from clenching position, thus tendingto more completely close the hook ears, the clencher tool beingwithdrawn before the cover reaches a position where it might grip orbite on the tool.

Obviously, this particular timing may be varied as desired, the generalarrangement shown` however, being such that it is possible to providemovements of parts in overlapping relation and without interference,thus permittimgr the completion of the operation to take place within aminimum space of time.

From the above it will be understood that the advancing movement of thebody blank is with its major axis extending in a vertical plane. thusproviding. a minimum supporting contact with the curved side of theblank. thereby tending to reduce the liability ot det'aeing the front orrear walls of the body portion which generallyv contain advcrtisingmatter, the general practice being to provide the finished surface tothe blank while in sheet form and prior to its being formed into thebody blank shown. While this` blank is clamped in position during theassembling operation, no movement of the body blank taires place duringthis period in which it is clamped` so that substantially no liabilityof defacing the exposed surface of the blank is had b v the clampingaction, it heilig understood, of course, that the clamping mechanism ofthe body blank is released prior to the succeeding advance of the bodyblank.

It will also be understood that the major axis of the cover also extendsvertically, and that the advancing movement oi' the cover is in adirection transverse to thc major axes of both cover and body blanks. lnother words, the direction of movement ot' the cover in advancing fromits fcd position to its assembly position is substantially transverse tothe direction of travel of the body blank, all movements ot' the coverblank after reaching a. point where interference with the body blank ispossible taking place While the body blank is stationary :ind held inclamped position, thus placing the openings into which cover blank hooksare to pass at a definite point and maintained at such point during theentrance of the hooks and the succeeding clcnching operation.

In this connection. it may be noted that accuracy in the advancing otthe body blank into the operating station is not matcriaL as long assuch advance is sutiirient to provide contact with the rear tace oiE theclencher tool at the time when the body blank reaches its clampedposition Should thc advance of the blank not bring it into contact withthe tool or have advanced it at a comparatively rapid speed and caused aslight rebound, such action is immaterial, due to the fact that the faceot' the tool inclines both to the longitudinal and transverse directionsof the runway, so that when the blank is shitted laterally, it will bebrought into contact with this face and will be carried to the properpoint. This more or less flexibility in delivery of the body blank intothe operating station is of advantage in providing e apparatusoperations ot' comparatively large capacity,

since the advancing mechanism may move with considerable speed withouttending to affect the position ot the body blank in the assemblingoperation. And since both blanks are clamped at least to the time ofapproximate completion of the clenching operation, the operating partsin the manipulating station may also operate athigh speed, the bodyblank remaining clamped until the cover is closed` clamping of the covernot being required after it has been assembled and its hooks clenched.

As will be seen, the body blank is advanced with an open end foremost`this end being that to which the cover is to be applied. Since thc bodyblanksl are more ,or less tubular in cross-sectional contourwhether thecover is applied before or after the bottoni is placed in position--tbeadvance ot' the body blank with its open end toremost enables the use ofmore compact form of mechanism and providesl t'or minimum contact of theapparatus with the blank dln'- `ingr thc advancing movement, thustending io materially reduce liability ol" dctacin; ry the blank.inasmuch as the blank is advanced in this manner and in practically asingle plane from the time it enters into the apparatus until it isdischarged therefrom, the cover blank is retained out. of such path of`ing action being as travel of the body blank excepting at thc time whenit is being advanced to assembly position. at which time it is carriedsubstantially transversely across such open end, the clamping andadvancing instrumentality for the cover moving in what may be consideredas a single plane in carrying the cover blank to this position. This isof advantage in that each type oi' blank has its advancing movementsprovided by mechanisms individual to itself, so that each advancingmechanism operates to present its blank at a predetermined point and thedelivery otl the lank at this point insures absolute registration of thecover blank and body blank, en-

abling the use of simple and etlicient meI chanical structures forproducing the result. And after the complemental blanks are assembled,the clencher tool is made active and the cover closed. As a result, thecomplemental blanks have no movements in unison as an assembled orpartially assembled structure while the hinge connection is incomplete,the only movements of this type taking place after thc hinging operationhas been completed, so that there is no liability of displacement ofparts or possibility/"of shifting or disturbance ot' the relation of oneot' the complemental blanks to the other after the. two blanks have beenbrought into proximitv to each other, all movements of the blanks priorto the completion ot' the hingindividuals, subsequent movements beingthose of a completely hinged structure.

While theparticular embodiment herein shown and described is adapted tooperate in connection with blanks ot' a more or less ovalcross-sectional contour, it will be readily understood that theprinciples of the invention are not limited to use in this connection`be- 1n adapted for use with containers of various otlier cross-sectionalcontours by changing the mechanical features -`in such manner as toaccommodate for the changed form of the container- Hence the inventionmay be employed in connection with curved orangular containers asdesired and such general use is contemplated by the invention.

While there is shown and described a prefer'red embodiment of theinventioisit -will be readily understood that variations andmodifications therein as to general arrangement and u iechanicalstructure of individual instrumentalitics may be found necessary ordesirable to moet the various exigencies of use to which the inventionmay be applied, and it is therefore to be understood that reservation ismade ot' the right to make any and all such changes as may be foundnecessary or desirable in so far as the same may fall within the spiritand scope of the invention as expressed in the accompanying claims whenbroadly construed.
